Here’s what HIVE AI had to say about “What international tax treaties affect filings this year?”:
Which tax treaties can materially affect U.S. filings in the 2026 filing season (generally for 2025 returns)
Treaties don’t change the basic requirement to file when you otherwise must file, but they can change the U.S. tax result (rate, exemption, sourcing, permanent establishment, residency tie-breaker), and can trigger specific disclosure/documentation requirements. 1
Treaty changes or limitations that are most likely to affect “this year’s” returns
- U.S.–Russia income tax treaty: the U.S. has partially suspended key operative articles and the protocol effective August 16, 2024. As a result, for payments made on or after August 16, 2024, withholding agents generally may not accept treaty claims that would reduce withholding below the statutory 30% on U.S.-source FDAP payments that previously could have qualified for treaty benefits. 1 2
- U.S.–Hungary income tax treaty: the treaty terminated January 8, 2023, and generally ceased to have effect for withholding at source and for other taxes for periods beginning on or after January 1, 2024. This impacts 2025 returns where taxpayers might otherwise have claimed Hungarian treaty benefits for U.S. tax purposes. 3
- U.S.–U.S.S.R. treaty still applies to certain countries: the IRS notes the U.S.–U.S.S.R. income tax treaty remains in effect for Armenia, Azerbaijan, Belarus, Georgia, Kyrgyzstan, Moldova, Tajikistan, Turkmenistan, and Uzbekistan. 2
- Belarus (under the U.S.–U.S.S.R. treaty): the IRS describes a partial suspension as it relates to Belarus effective December 17, 2024, continuing until December 31, 2026 (unless ended earlier). This can affect treaty claims tied to the suspended provision for 2025 and 2026 filings involving Belarus residency. 4
A treaty doesn’t affect your return unless you are actually claiming a treaty benefit (and then disclosure may be required)
- If you take a treaty-based position that reduces or overrides U.S. tax (including treaty residency “tie-breaker” positions), you generally must disclose it on Form 8833, unless an exception applies. 3 4
How to identify which specific treaty provisions apply to your filing
- The IRS “Tax treaty tables” are the practical starting point for common categories of U.S.-source income (interest, dividends, royalties, pensions, compensation, etc.) and the Limitation on Benefits (LOB) framework, but you still must consult the actual treaty text/protocols for eligibility and conditions. 5 5
If you tell me (1) your country of residence for 2025, (2) your U.S. filing status (U.S. person abroad vs. nonresident filing 1040-NR), and (3) the type of income (wages, dividends, royalties, pension, business profits, etc.), I can narrow this to the treaty articles that most commonly affect that fact pattern.
